“…Tudor cultivar also had a good n-6/n-3 fatty acids ratio (3.02), a high content of n-3 PUFAs (14.34%) and a high total lipids content. Due to its location, Dobrogea region (southeast of Romania) offers ideal climate and soil conditions for apricot culture [ 2 ]. In order to validate these results, the same cultivars should be tested in different geographic regions and during several years.…”

“…Both farms are located in the Constanța County, southeast of Romania, between the Danube River and the Black Sea. This region has a temperate-continental climate with an average yearly temperature of 10.7 °C, characterized by mild winters with the lowest temperatures rarely descending below −17 °C and warm and very arid summers (200–250 mm during the active period [ 2 ]. The fruits were collected between 25 June–15 August 2014, when fully ripe according to their color and firmness.…”

“…Romania produced more than 35,000 t of apricots in 2018 and is one of the leading European countries in apricot breeding, with a collection of more than 630 genotypes originating from different geographical areas in the world. In the frame of a large apricot improvement program which started in 1971, more than 40 new cultivars have been obtained by fruit research institutes [ 1 , 2 ].…”

Carotenoids, Fatty Acids, and Volatile Compounds in Apricot Cultivars from Romania—A Chemometric Approach

et al. 2020

Lipophilic constituents are important for the color and aroma of apricots, but also for their health benefits. In the present study, carotenoids, fatty acids, and volatiles were analyzed in 11 apricot cultivars, from which nine were obtained in Romania. High performance liquid chromatography coupled to a diode array detector with atmospheric pressure chemical ionization and mass spectrometry (HPLC-DAD-APCI-MS methodology applied on unsaponified carotenoid extracts allowed the identification and quantification of 19 compounds. The predominant carotenoids in all cultivars were all-trans-β-carotene and its cis isomers. Lutein was present exclusively in non-esterified form, while β-cryptoxanthin was predominantly esterified, mainly with oleic, palmitic, lauric, and stearic acid. Moreover, β-cryptoxanthin linoleate, linolenate, and stearate were detected for the first time in Harogem cultivar. Variation in carotenoid content and composition was observed, with the highest carotenoid content being recorded in Tudor, Harogem, and Mamaia cultivars. The predominant fatty acids determined by gas chromatography–mass spectrometry (GC-MS) were linoleic (up to 47%), palmitic (up to 32.7%), and linolenic (up to 17.16%), with small variations among cultivars. In-tube extraction technique (ITEX)/GC-MS was applied for profiling the volatiles in apricot fruits and 120 compounds were identified, with terpenoids and esters as the most abundant classes. Principal component analysis (PCA) revealed that the carotenoids and the fatty acids profile can be used for variety authentication and discrimination in apricots.

“…The increasing number of self-incompatible cultivars in the last years can be explained by using Asian or North American self-incompatible cultivars in breeding programmes that aim to create new genotypes with the traits such as: Plum pox virus resistance (Badenes, Llácer 2006;Karayiannis 2006;Krška et al 2011), frost tolerance (Benediková 2006;Krška et al 2006), increase of the sugar content (Ledbetter et al 2006), or extending the harvest time (Pedryc, Kerek 1999;Topor et al 2010). Some of the self-incompatible cultivars are frequently used in apricot breeding programmes.…”

Testing of self-(in)compatibility in apricot cultivars from European breeding programmes

2013

View full text Add to dashboard Cite

Self-(in)compatibility was tested in 40 new apricot cultivars from European breeding programmes. Pollen-tube growth in pistils from laboratory pollinations was analysed using the fluorescence microscopy. Cultivars were considered self-compatible if at least one pollen tube reached the ovary in the majority of pistils. Cultivars were considered selfincompatible if the growth of pollen tubes in the style stopped along with formation of characteristic swellings. Of the examined cultivars, 18 were self-compatible and 22 were self-incompatible. Fluorescence microscopy provides a relatively rapid and reliable method to determine self-incompatibility in apricot cultivars.

“…The cultivars examined in the present work originated from this breeding programme. It is planned to continue these tests on the latest cultivars developed by Romanian breeders (Topor et al, 2010). In Canada, too, an improvement in frost tolerance and winter hardiness is an important aim in apricot breeding (Layne, 1978(Layne, , 1979(Layne, , 1981Layne and Gadsby, 1995).…”

Like all phenological processes, microsporogenesis is mainly determined genetically, but its phenotypical expression is greatly influenced by environmental factors, particularly the temperature. During the 3-year experimental period, the process of microsporogenesis was examined in eight apricot cultivars originated in North America and in Romania. The Hungarian cultivar ‘Gönci magyar kajszi’ was used as the control. Based on the results it was possible to rank the cultivars in terms of their microsporogenesis schedule. The same order was found in all three years. This order also indicates the yield reliability of the cultivars. Endodormancy ended between January 10th and 25th in the buds of the earliest cultivar ‘Pinkcot’, but not until February 5-10th in the latest cultivar ‘Harlayne’. Three of the cultivars had faster flower bud development than the control, in the order ‘Pinkcot’, ‘Orange Red’ and ‘Harcot’. Growing these cultivars thus involves greater risk than for ‘Gönci magyar kajszi’ in Hungary, due to their rapid winter flower bud development. Some cultivars found to have slower flower bud development than ‘Gönci magyar kajszi’; ‘Litoral’, ‘Harogem’, ‘Comandor’, ‘Sirena’ and ‘Harlayne’ – thus these cultivars can be grown more reliably.
